hi, This question is about how I can detect whether a system is low on memory. Consider a finite state automaton consisting of just 2 states. The first state is where the system is ok with memory and the second state is where its low on real memory. In that what events in the kernel can give me an indication that the system is progressing towards a low memory state, these events would be the labels of the arcs from the state 1 to state 2. Similarly there would be a arcs from state 2 to state 1 which would imply the actions taken by the OS to revive itself. Any help in this matter will be appreciated. thanks, amit __________________________________________________ Do You Yahoo!? Yahoo!
